 it would require someone who can write a BDOS for it. 
 At the risk of appearing negative, I do not think the world needs
 another single-board CP/M computer at this moment in time. 
That may very well be.
I figured if I developed a cart that could
function standalone, then I have two chances for usefulness.
 In any event, I think it's the BIOS that will be required.  There are
 plenty of free options for CCP, BDOS and utility suites. 
Yes, as others had noted.
I'll not feel bad, as I started my thread
noting I have a very weak understanding of CP/M.
That said, I think there is a market at least for an open source
schematic of a minimal CP/M system.  Something that used SD cards, had 2
UARTS (one for terminal, one for modem/etc.).  People like me could use
it as the basis for learning the environment without needing to find a
classic machine, and then not knowing how to prepare floppies for it.  I
can attest that many more folks are interested in their CBM machines now
that there are CF and SD (FAT-compatible) drives for them.
Of course, I should point out at this point that I release all of my
designs as open source, to guard against orphan projects/products with
no ability to re-use.  Thus, if someone is not a fan of open source, we
probably won't find much in common on such a project.
